Abstract

PURPOSE: To attain a variety of antirolling frequencies by installing a slanting partition in each side of U tube type antirolling water tank to divided the room into a reserved water tank and a main water tank, and introducing water from the reserved water tank into the main water tank by means of compressed air.
CONSTITUTION: Water tanks at each side are connected at the bottom by a water duct 1 forming a U tube type antirolling water tank. A slanting partition 2 is installed in each water tank 10 dividing it into a reserved water tank 4 and a main water tank 3. The main water tanks at each side are connected by an air duct 6. The main water tank 3 and the reserved water tank 4 of the water tank 10 at one side is connected by a pipe 8 which is connected to a compressed air source 7. An opening equipped with a valve 13, 14 is provided to each of the main water tank 3 and the reserved water tank 4 of the opposite side water tank. When compressed air is introduced into the tank 4, water will be forced through an opening 5 into the tank 3. On the contrary, if the charged air pressure is reduced, water will be withdrawn back into the tank 4.
